crashes

Thu Dec 10 07:23:49 GMT 2020

After cloning and compiling stellarsolver, and NOT running gdb (OK next
time I'll try that 'set handle SIG32 nostop noprint' magic) everything
seems to be running. I'm going to chalk this one up to some StellarSolver
incompatibility between it and KStars, unless I see more crashes.
